Answer this question truthfully
### Question: What causes Rubella?
### Response: The disease is caused by a virus that is spread through the air or by close contact.
A person can transmit the disease from 1 week before the rash begins, until 1 - 2 weeks after the rash disappears. The disease is less contagious than rubeola (measles). After an infection, people have immunity to the disease for the rest of their lives.
In children and adults, rubella is usually mild and may even go unnoticed.
